다국어 초록 (Multilingual Abstract)

This paper presents the design for a security system for the construction of Intranet. The great Internet explosion during the past two or three years is largely fueled by the prospect of performing business online and other areas. Furthermore, Intranet interest have exploded in the last few years But, on existing security framework are lack and many problems. Therefore, we propose to design a new security system(firewall-like) for the Intranet systems.
The proposed security system consists of 3 parts : internal, bastion host, and external. The internal part consists of LAN(including a screen router) and host, internet service servers The bastion host has several gateway modules(FTP, SMTP, NNTP, etc) The external part consists of DMZ(including a public sorter and screen router) and Internet connection interface devices. The new security system is almost completely guaranteed as it has been checked three times.
